preparation example Construction

[0053] During the manufacturing process of the display device, it is also necessary to bond the bonding region T1 of the touch substrate 2 to the touch flexible circuit board 6 so as to electrically connect them to each other. Since the film thickness of the touch substrate 2 is small (less than 0.05mm), the bonding width is small and the strength is weak. In practical applications, the touch flexible circuit board 6 needs to be bent to the backlight side of the display panel for fixing. However, when the touch flexible circuit board 6 is bent, due to the concentration of pulling stress on the touch flexible circuit board 6 , the circuit on the touch control substrate 2 may be easily broken. Moreover, due to the existence of the first adhesive layer 3 , there is a gap d1 between the flexible display panel 1 and the touch substrate 2 . When the second adhesive layer 5 is bonded to the touch-sensitive flexible circuit board 6 in the binding area T1, the binding area T1 is easil...

Abstract

The invention discloses a display device and a preparation method thereof, and the display device can realize a touch function by combining a flexible display panel with a touch substrate through a first bonding layer and enabling an effective touch area to cover a display area. Moreover, a supporting layer is filled in a gap between the touch substrate and the flexible display panel, and the orthographic projection of the supporting layer on the flexible substrate at least covers the area, directly facing the step area, of the binding area, so that the gap between the touch substrate and the flexible display panel can be filled, the strength of the binding area can be improved, and the risk of line bending and breaking can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a preparation method thereof. Background technique [0002] Generally, a flexible printed circuit (FPC) is assembled in a display device to transmit signals through the flexible printed circuit. Stress will occur during the preparation of the flexible circuit board, and the stress will lead to the risk of disconnection at the binding part of the flexible circuit board, resulting in a decrease in the reliability of the display device. Contents of the invention [0003] Embodiments of the present invention provide a display device and a manufacturing method thereof, so as to improve the reliability of the display device. [0004] An embodiment of the present invention provides a display device, including: [0005] A flexible display panel, including: a flexible substrate, the flexible substrate includes a display area, a step area and a bending area arrang...
